Her breasts were small like Sarah's. She had the same tiny nipples as Sarah did. She had the same hands, too, as I had just recently found out. Her flesh was enticing, but I felt very hesitant. I felt like I was cheating on the woman that I loved. I hadn't been with anyone else but Sarah for four years now, and here was her own flesh and blood inviting me in for the taking.
Chloe sensed this and stepped back a step. Still smiling, though, she began to lather up with my wife's body wash.
"Are you mad at us?" she asked.
"No, Chloe. Admit it though, this is kind of fucked up, isn't it?" I said as I slowly reached out to touch her hot, wet skin, stopping only an inch away.
"Don't fight it, Michael. Really, I've wanted you for a long time. Sarah isn't stupid. She knows you want me. That's why she's doing this," Chloe said as she finished soaping her body.
She moved past me to rinse off. Her slippery body rubbed across me, her flesh caressing every inch of me that faced her. As I turned with her, my hard cock slipped in between her thighs and across her smooth pussy. I definitely wanted her. I wanted to be in her right now. She knew it, too. She stopped and spread her legs slightly as she looked into my eyes. My chest tightened as I felt her wet labia on my cock. Involuntarily, I eased forward slightly and felt myself slip across them. We gasped together as her soapy chest pushed against me. This was it, I couldn't take any more. Chloe Lawson, my wife's sister, was mine. We kissed deeply as I picked her tiny body up in my arms, my strength fueled by passion. She giggled and licked my neck as I thrust at her, sliding deep into her wet hole. She was tight and warm, inviting me deeper and deeper. Her pretty, innocent face shined in the dark shower, her soft lips curling from our pleasure. I felt like an animal, on fire and hungering for her flesh. I fucked her hard as I gripped her body tight. The new sensation of a different woman's pussy overwhelmed me. They were very similar, but just different enough for me to know, full and well, that it was Chloe I was inside of. It was just enough to know that I was sharing something that I had shared with only one other woman in four years. Chloe had always been separate from me, always platonic and off-limits. The world had changed suddenly with what was happening now.
"Oh, God, fuck me Michael! Come inside me!" she moaned in my ear.
"Oh, fuck, Chloe, I can't believe this!" I said as I thrust harder and harder.
We fell out of the shower and onto the rug as we kissed and nibbled each other all over. It was an orgy of flesh and plastic; Chloe and I twisting under the shower curtain together. The plastic stuck to us as we fucked and fucked, crinkling from our motion. The new flesh, the strange skin wrapped around my cock, Her moaning; it was all consuming me as I tasted her kisses and smelled her excitement beneath me. Her body, a stranger's body, moved under me differently than Sarah's, but it was still so very familiar; as if Chloe knew what to do to give me the most. She licked me and rubbed her hands across my ass, grabbing it and pulling me deeper into her. She bit my neck and began to moan lauder and louder. This was it. She was close.
"Oh, Michael, I'm coming! Oh, yeah, fuck me!" she said as she tensed up and arched beneath me.
I watched her smile and bite her lip, lost in the waves of pleasure. I was close, so close to filling her up. This was unbelievable! Chloe's wet, soapy body stretched out underneath me as she ran her hands down my back.
"Come on baby, come in me. I want it, baby," she said as she squeezed her vagina muscles around my cock.
As I closed in on my orgasm, the room filled with light. Sarah, out of the corner of my eye, was standing there watching us from the doorway. As I looked up at her, I began to come in her sister. Sarah's eyes were on fire, enjoying the show immensely. I looked down at Chloe as I began to squirt my hot load deep within her. I gasped as I felt the wave of my orgasm consume me. Chloe was mine. I had come deep within her as my wife watched with approval. What a day.
"You broke the shower, lover," Sarah said.
Chloe laughed as I rolled off of her and into cold, wet plastic.
